  Product information

Product names

  • RubberGard™ Max (Reinforced) EPDM Membrane
  • RubberGard™ Max PT Membrane

Product description

All the membranes are single-ply, reinforced, type II, black, ethylene-propylene-diene terpolymer (EPDM) roofing membranes with 3.05 m (10 ft.) widths and 30.5 m (100 ft.) lengths.

The “RubberGard™ Max (Reinforced) EPDM Membrane” is available in thicknesses of 1.14 mm (45 mil), 1.52 mm (60 mil) and 1.91 mm (75 mil).

The “RubberGard™ Max PT Membrane” is available in a 1.52 mm (60 mil) thickness. A 152.4-mm (6-in.)-wide piece of QuickSeam™ tape is factory-laminated along one 30.5 m (100 ft.) length of the sheet.

Wind Uplift Resistance of Membrane Roofing Assemblies

The wind uplift resistance performance rating is based on CAN/CSA-A123.21-14, “Dynamic Wind Uplift Resistance of Membrane-Roofing Systems.”

The following membranes used in the roofing assembly achieved a factored dynamic wind uplift resistance of either –2.4 kPa (–50 psf) or –3.19 kPa (–66.7 psf), depending on the assembly, when using CAN/CSA-A123.21 test method 2 for Adhesive Apply Roof Systems:

  • “Rubbergard™ Max (Reinforced) EPDM Membrane”
  • “Rubbergard™ Max PT Membrane”

For details on the roofing assembly, see PRI Construction Materials Technologies test report FBP-393-02-01.

The following membranes used in the roofing assembly passed all levels with a factored dynamic wind uplift resistance of –2.9 kPa (–60 psf) when using CAN/CSA-A123.21 test method 1 for Mechanically Attached Roof Systems:

  • “Rubbergard™ Max (Reinforced) EPDM Membrane”
  • “Rubbergard™ Max PT Membrane”

For details on the roofing assembly, see EXP Services Inc. test report FBPS-DRC-00211230-07-5100.

Administrative information


This evaluation is issued by the Canadian Construction Materials Centre (CCMC), part of the Construction Research Centre at the National Research Council of Canada (NRC). The evaluation must be read in the context of the entire CCMC Registry of Product Assessments and the legislated applicable building code in effect.

The CCMC was established in 1988 on behalf of the applicable regulator (i.e., the provinces and territories) to ensure—through assessment—conformity of alternative and acceptable solutions to regional building codes as determined by the local authority having jurisdiction (AHJ) as part of the issuance of a building permit.

It is the responsibility of the local AHJs, design professionals, and specifiers to confirm that the evaluation is current and has not been withdrawn or superseded by a later issue. Please refer to the website or contact:

The NRC has evaluated the material, product, system or service described herein only for those characteristics stated herein. The information and opinions in this evaluation are directed to those who have the appropriate degree of experience to use and apply its contents (i.e., AHJs, design professionals and specifiers). This evaluation is only valid when the product is installed in strict compliance with the stated conditions and limitations of evaluation and the applicable local building code. In circumstances where no applicable local building permit is issued and that no confirmation of compliance ‘for use in the intended field application’ is undertaken, this evaluation is null and void in all respects. This evaluation is provided without representation, warranty, or guarantee of any kind, expressed, or implied, and the NRC provides no endorsement for any evaluated material, product, system or service described herein. The NRC accepts no responsibility whatsoever arising in any way from any and all use and reliance on the information contained in this evaluation with respect to its compliance to the referenced code(s) and standard(s).
